Following are the different types of Control break statements.
AT FIRST: - This event is triggered at the first record of an internal table. This is used to display the Header information.
AT NEW: - This event is triggered at the first record of each block. This is used to display the individual headings.
AT END OF: - This event is triggered at the last record of each block. This is used to display the total/sub totals in the internal table.
AT LAST: - This event is triggered at the last record of an internal table.
ON CHANGE OF: - It is a special control break statement which can be used outside of the loop statement also.
